With the progress of mobile GIS technology there is a great potential for adopting wireless communications and Internet mapping services for regional environmental management programs and natural habitat conservation. This paper provides an overview of a NASA-funded research project that focuses on the development of mobile GIS tools and wireless Internet Map Server (IMS) services to facilitate...

The format of space data used in Geographic Information System (GIS) is different currently, therefore, exchange the GIS data among different GIS applications is not very convenient. In order to solve the problems, we take three methods. Firstly, the storage format of the shape document series (*shp, *shx and *dbf) is analyzed. Secondly, we study the technologies and methods of changing the sha...

This study develops a geographical information system (GIS) approach for automated processing of the Next Generation Weather Radar (NEXRAD) Stage III precipitation data. The automated processing system, implemented by using commercial GIS and a number of Perl scripts and C/C++ programs, allows for rapid data display, requires less storage capacity, and provides the analytical and data visualiza...

Remote Sensing (RS) and Geographic Information System (GIS) education and implementation is rapidly being adopted by universities in developing countries, such as the United Arab Emirates (UAE). Until recently, the use of GIS and RS in education in the UAE was hindered by the cost of hardware and the complexity of software. With the price/performance increase of desktop computer capabilities an...

Networking GIS tools and applications vary greatly in both function and architecture. In this paper, we will provide a framework to study the problems of networking GIS. GIS resources consist of geodata and geoprocessing capabilities. From the viewpoint of geodata sharing, it is observed that decoupling geodata and geoprocessing is necessary given the difficulty of integrating autonomous GIS sy...

Data in Geo Information Systems (GIS) is used for map services and various applications. Thus, quality assessment on a regular basis is required to keep the data up-to-date. In this paper we focus on one key reasons for updates: incorrect object borders. State of the art systems semi-automatically analyse up-to-date satellite image data to narrow down areas that have to be considered for GIS up...

Geographic information systems (GIS), global positioning systems and remote sensing have been increasingly used in public health settings since the 1990s, but application of these methods in humanitarian emergencies has been less documented. Recent areas of application of GIS methods in humanitarian emergencies include hazard, vulnerability, and risk assessments; rapid assessment and survey met...

This paper presents a post-classification approach that can achieve efficient results for change detection by using AdaBoost classifier. In the first step, a land cover of satellite image is classified in the independent fashion. For the stable classification of man-made structures, 3D features are employed. 3D co-occurrence feature is used with 2D co-occurrence feature and Harr-like feature. A...

Streamlined and efficient data maintenance processes are crucial to maintaining a GIS. Re-engineering of existing business processes in advance of data conversion is at the heart of ensuring that data is effectively maintained during and after conversion. Charlotte-Mecklenburg Utilities, (Utilities) has initiated a GIS Foundation project to convert its water and sewer system data into a GIS. Th...

The relationship between critical geography and geoinformatics has recently entered a new phase of cordiality and constructive discourse, exemplified by the NCGIA Initiative 19 [27], the Varenius project [21] and a variety of journal special issues on the topic of GIS and society (eg [28]). This new-found entente has opened the way to the re-evaluation of existing GIS-based research and to much...
